Abstract
The technology relates to technology for detecting a predetermined image using a template of the predetermined image. The method includes detecting a color, reducing the color to a range of the color, converting to a grayscale plurality of images, extracting at least one edge of the grayscale images, identifying each component in the images, conducting binarization for the each component, obtaining a threshold value, normalizing the template, and matching the template to the predetermined image.
